SPRING-FRAME FOR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented July 2, 1918.

Application filed October 19, 1917. Serial No. 197,477.

To all whom it may concern:

Be it known that JOSEPH PRONOVOS'I, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, hasinvented certain new and useful Improvements in Spring-Frames forVehicle-VVheelsz and he does hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, refer ence being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in spring framesfor use upon vehicle wheels, with a view of afi'ording efficient meansto take up vibration incident to a wheel passing over rough roads orobstacles, and serving as a substitute for a pneumatic tire.

The present invention consists in the provision of a device of thisnature, having various details of construction and combinations ofparts, and generally improving upon the form of spring apparatus coveredby my Patent #l,22(),889.

provided with oppositely disposed elongated slots A each slotterminating at corresponding ends in a circular outlined portion A Themember A has one end bent, as at A and has a concaved portion A and anend portion A bent parallel to the oppositely disposed elongatedportions of the member and engages an inwardly turned portion A near theother end of the member. The second end of the member A is concaved,

or hook-shaped, as at A and rests against the inner convcxed portion ofthe hooked end.

The member B has oppositely disposed slotsB' and at corresponding endsopposite those in the member A has circular outlined portions 13 D hasoppositely disposed recesses E the portions ofthe block intermediatesaid recesses being adapted to be guided in the registering slots in thetwo members A and B. The opposite faces of said block, intermediate thetwo members A and B, are concaved, as at F, the recess upon the outerface of the block being adapted to contact with a pin or roller H,adapted to be connecter to the disk or hub portion H of a wheel.

A spring, designated by letter N, is bent at its longitudinal center,forming a crosspiece O, which engages the hooked end of the member A,the arms of the wire being bent to form coils R, and the free ends ofthe wire are passed through registering slots in the two members A andB, and the angled ends T of the wire, which extend in oppositedirections, engage the concaved recess in the face of the block Dholding the latter against the inwardly turned ends B of the member B. Apin or roller, designated by letter S, is adapted to be positionedintermediate the concaved recess formed in the 7 'member A and theadjacent concaved por tion of the member B.

It will be noted upon reference to the drawings that the angled ends Tof the spring extend around the corners intermediate the two concavedsurfaces and interlocking therewith. in such a manner as to prevent thedevice rattling, and aiiording substantial means for holding the ends ofthe wire in proper relation with the block.

What I claim to be new is:

1. A spring frame for vehicle whee-ls, comprising two U-shaped membershaving sliding connection with each other and provided with oppositelydisposed registering slots, the ends of the inner of said members beingbent to over-lap each other in opposite directions, a block havingcontracted portions movable within said slots, a coiled spring bent uponitself at its longitudinal center and engaging the inner of said bentends, the arms of the wire extending A movable cross-piece orblockthrough registering slots in said members and having ends bent inopposite directions and engaging the inner face of said block.

2. A spring frame for vehicle wheels, comprising two U-shaped membershaving sliding connections with each other and provided with oppositelydisposed registering slots, the ends of the inner of said members beingbent to over-lap each other in opposite directions, a block movablewithin said slot, the opposite faces of said block being concaved, aspring bent upon itself at its longitudinal center and engaging theinner of said over-lapping ends, the arms of the spring passing throughregistering slots in said members, and having right-angled ends disposedin opposite directions and engaging one of the grooves in said block.

8. A spring frame for vehicle wheels, comprising two U-shaped membershaving sliding connections with each other and provided with oppositelydisposed registering slots, the ends of the inner of said members beingbent in opposite directions and over lapping each other, the ends of theouter member bent in opposite directions and against the outer facethereof, a block having oppositely disposed recesses, the contractedportions intermediate the recesses engaging registering slots in themembers, a

coiled spring bent upon itself at its longitudinal center and engagingthe inner of said overlapping ends, the ends of the spring bent atangles and engaging the inner face of said block.

4. A spring frame for vehicle wheels, comprising two U-shaped membershaving sliding connections with each other and provided with oppositelydisposed registering slots, each having corresponding ends terminatingin enlarged circular outlined por tions, the ends of the inner memberbent to overlap each other, the outer over-lapping portion beingconcaved and the inner end formed into a. hook, a block havingcontracted portions movable within registering slots in said members,the opposite faces of the block being concaved, a coiled spring bentupon itself at its longitudinal center and engaging said hooked end, thearms of the spring passing through registering slots in the members'andterminating in angled ends engaging the grooved ends of said block.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
